pected. Seventy-five per cent of the staked plants of this variety were deter- 

 minate, some producing only one cluster of fruit, and others ranging from two to 

 four clustere. (irown flat, the growth was normal. Fruit was of good size and 

 quality, but a large proportion showed an objectionable yellow under-color similar 

 to that of Break O'Day. There is always much interest in our tomato trials on 

 the part of all growers who visit the Field Station. Peculiar as it may seem, there 

 is no variety which is outstanding year after year; therefore, it is difficult to make 

 definite variety or strain recommendations to growers. Seasonal conditions aft'ect 

 the growth of tomatoes considerably. 



Beans were included in the trials this year on account of the many new variety 

 names found in the seed catalogues. There is a distinct trend in popularity 

 toward the more extensive use of the round-podded varieties. Although the 

 flat podded varieties Bountiful (green pod) and Sure Crop (wax) are still the 

 most popular, there is more interest than ever in Pencil Pod Wax and the new 

 round pod varieties Tendergreen and Stringless Black Valentine. 



Twenty celery varieties made an exceptionally good growth in spite of the 

 abnormally dry season. New variety names appearing this year in our trials 

 were Golden Phenomenal, Golden Detroit, Utah Golden Crisp, Salt Lake, and 

 Florida Queen. It will be necessary to try all of these again before final judgment 

 is passed. Up to date, there is no reason for recommending that our growers 

 make any change from the varieties they are now growing — Pascal for winter 

 and Golden Plume or Wonderful for summer and fall. 



New names appearing on the variety lists of carrots also made it imperative to 

 conduct a carrot variety test this year. Perfection, Pride of Denmark, and 

 Imperator are very similar in type to the Coreless although much larger. All are 

 uneven in size and type. Both favorable and unfavorable comments have been 

 received from growers on all these varieties, so it is recommended that a grower 

 determine just how each one performs unfler his conditions before planting any 

 quantity. The new Red Cored Chantenay is certainly a big improvement 

 in quality and the type is exceptionally uniform. Tendersweet, apparently a 

 strain of Red Intermediate, is a carrot of exceptional quality and similar in color 

 to the Red Cored Chantenay. Many local market gardeners are now using the 

 Hutchinson variety for bunching, in place of the C^hantenay and Danvers varieties 

 formerly used for this purpose. 



COOPERATIVE CRANBERRY INVESTIGATIONS 

 Conducted by the Bureau of Plant Industry, United States Department 

 of Agriculture, in cooperation with the Massachusetts Agricultural 

 Experiment Station. H. F. Bergman, Senior Pathologist, U.S.D.A., in

Development of Strains of Cranberry Resistant to False Blossom. 



(H. F. Bergman, W. E. Truran, and Jos. L. Kelley.) Reciprocal crosses between 

 Early Blacks and McFariins were made in July 1932. The crosses of F:arly Black 

 by McFarlin were unsuccessful. The reciprocal cross of McFarlin by Early Black 

 yielded a considerable number of fruits which matured normally. In order to 

 determine the possible existence of resistant strains within single varieties, a 

 number of flowers of the varieties Early Black, McFarlin, and Howes were self- 

 pollinated. No fruits were obtained from selfetl flowers of Early Black, but 

 fruits were obtained from both the other varieties.
